Evaluation of the Performance of Parental Lines and their F1 Hybrids for Yield and Attributing Traits in Vegetable Pea [Pisum sativum (L.) var. hortense]

Abstract

The present investigation was carried out to obtain information based on per se performances of parents and their combinations for genetic improvement in vegetable pea. Ten promising genotypes were crossed in a diallel manner (excluding reciprocals). Half diallel set of 45 F1’s in vegetable pea was evaluated in Randomized Complete Block Design (RBD) with three replications for eighteen yield and yield attributing traits during Rabi 2020-21 (Y1) and 2021-22 (Y2) at the Main Experimental Station (MES), Department of Vegetable Science, Acharya Narendra Deva University of Agriculture and Technology, Narendra Nagar, Kumarganj, Ayodhya (U.P.) India. The study evident that highly significant differences were observed for most of the traits under study. Based on per se performance, parent P10 (60.84 g) exhibited the highest green pod yield per plant followed by P5 (55.80 g). The per se performance of crosses i.e. P7 x P10 (81.88 g) followed by P6 x P10 (81.87 g), P5 x P10 (79.66 g) and P5 x P7 (78.89 g) produced significantly higher green pod yield per plant than the general mean. These hybrids may be exploited as a new variety after selection and subjected to multi-locational trials for their release as cultivation on a commercial scale.

Evaluation of the Performance of Parental Lines and Their F1 Hybrids for Yield and Attributing Traits in Tomato (Solanum lycopersicum L.)

“…The selection of parents having high per se performance would be of merit in producing better hybrids and hence the parents selected for the crossing program were evaluated based on their per se performances. The most important trait fruit yield per plant and other quality traits results for pooled data are discussed below" [4]. A perusal of Table 1 revealed that days to 50% flowering ranged from 28.71 to 41.47 for parents and F 1 hybrids with an overall mean of 35.50.…”

“…The present investigation was carried out at the Main Experimental Station, Department of Vegetable Science, Acharya Narendra Deva University of Agriculture and Technology, Narendra Nagar (Kumarganj), Ayodhya (UP), India, during Rabi, 2021-22 (Y 1 ) and 2022-23 (Y 2 ). "The experimental farm falls under a humid subtropical climate and is located between 24.47° and 26.54°N latitude and 81.84° and 83.58°E longitude at an altitude of 98 m above mean sea level" [4].…”
